SEECIFICA'IION forming part of Letters Patent No. 681,624, dated August 27, 1901.

Application led May 8, 1901.

T all wwm it 7mo/,y concern:

Be it known that I, WILLIAM BARNUM COWLES, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in llflechanjsfnv for Moving Armored Hatches or other Heavy Barriers; and I do hereby declareh@ following to be afull, clear, and exact description of the invention, such as willfuable VOthers Skilled 111 the mi t0 WhChjftappertains to make and use the same. ,f

My Present/invention relates to improvements 1U aPlgfaratus for closing swinging doors O1 hLChQ, such as heavy armored hatches and Oblbtir like devices, and while it is espe- @muy `,l-nteuded for use on shipboard it may be Ud advantageously in other places where L hiavy hatchway or grating is to be lifted Oli-"swung out of the way.

l. My present-invention is intended to embody -tn adaptation of the general system shown in y United States Patents No. 631,698, grant- `fed August 27, 1899, and No. 656,947, granted j August 28, 1900, for the opening and closing ot heavy hatches either at a distance from one or more central stations or by hand at the hatch itself.

Y This invention is adapted to use Huid-pressure of any suitable kind; but I preferably employ pneumatic pressure stored up in a main reservoir for operating the mechanism from the central station and liquid-pressure generated in a hand-pump for operating each hatch separately by hand, as described in my Patent No. 656,947 aforesaid.

My invention will be better understood by reference to the accompanying drawings, in

, which the same parts are indicated by the same letters throughout the several views.

FigureV l represents a vertical section through an armored hatch and the adjacent parts ot the deck, the section being along the line l l ot' Fig. 6 and lookingin the direction of the arrows. Fig. 2 represents the section along the line 2 2 of Fig. 6 looking in the direction of the arrows and shows the means for operating the puppet-valve and handpump by hand from either side of the deck. Fig. 3 is a detail sectional View showing the tightening device for binding the hatch down lating the tighteners.

Fig. 5 is a detail view showing the Crank-arm and connecting-rods for oper- Fig. 6 represents an inverted plan View of a hatch when in a closed position and shows the mechanism for operating the same, and Fig. 7 is a detail sectional View showing the lock for controlling the operating-shaft which moves the tighteners.

A represents the armored or protective deck of a ship, which is placed over the deck-plating A and A2.

A3 represents abulk beam or girder,secul.ed to the under side of the deck.

B represents a hatch rabbeted, as shown at bo, and provided with a suitable packing b. This hatch is hinged at one side to the deck, as at C, and is swung upto the open position (indicated in dotted lines in Fig. l) by the mechanism that will hereinafter be described.

D is a rock-shaft journaled in bearings B', secured beneath the hatch. Said rock-shaft is provided with cranks D, having ears D2, projecting laterally therefrom. Links E are pivotally connected to the cranks D' and also to the bell-crank levers F, which are pivoted on the shaft G, journaled in bearings A4, secured to the under side of the deck. The piston-rod I-I is connected to a lug f on one of the bell-crank levers F by means of the pin h, and the said piston-rod projects into the cylinder H', which is trunnioned in bearings provided in the brackets A5, secured beneath the deck. Fluid-pressu re is su pplied at one end of the cylinder by means of the pipe K and is carried oft from the other end of the cylinder by means of the pipe K', or vice versa. In order to allow the cylinder I'I to rock through the desired angle and to obviate the necessity for stuffing-boxes in the trunnions, the pipes K and K' are coiled, as at 7c. Illuid-pressure from the main reservoir (not shown) is admitted through the pipe L to the valve mechanism M, which may be controlled by hand from either side of the deck by means of the handles M' and M2, (see Figs. 2 and 6,) and passes from this valve mechanism to the proper end of the cylinder. These two handles M' and M2 are or may be mounted on opposite ends of the Valvestem m. (See Fig. 2.) The handle M is IOO In order to lock the hatch firmlyon its seat,

65 ing or opening of the hatch may be provided While I have shown the invention as apagainst. plied to the fluid-pressure system described in my patents aforesaid, it will be obvious that the same may be operated by Huid-pressure from any suitable source or sources. It Will also be obvious that various modifications of the herein-described apparatus and in the combination and arrangement of parts may be iliade which can be used Without departing from the spirit of my invention.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent of the United States, is-
